Answer this question please:
When a motor neuron generates an action potential, it travels rapidly along the nerve until it reaches the neuromuscular junction, where it initiates an electrochemical process that causes acetylcholine to be released into the space between the presynaptic terminal and the muscle fiber. The acetylcholine molecules then bind to nicotinic ion-channel receptors on the muscle cell membrane, causing the ion channels to open. Calcium ions then flow into the muscle cell, initiating a sequence of steps that finally produce muscle contraction.

Answer this question: where is acetylcholine released from to stimulate muscle contraction?

Stream of random thoughts: The relevant information is: When a motor neuron generates an action potential, it travels rapidly along the nerve until it reaches the neuromuscular junction, where it initiates an electrochemical process that causes acetylcholine to be released into the space between the presynaptic terminal and the muscle fiber.... The answer is the neuromuscular junction.

A replica, depicted as a Carrack, was commissioned by the city of Columbus, Ohio. It was built by the Scarano Brothers Boat Building Company in Albany, New York, who later cut the ship in half and transported it by truck to the Scioto River. The replica cost about 1.2 million dollars. The ship was constructed out of white cedar as opposed to an oak wood used on the original to give the ship a long life in the Scioto River and to reduce cost. The main mast was carved out of a single douglas fir tree and was equipped with a top sail (since removed). The ship was built using power tools, with a hull length of 29.6 m (97 ft), keel length 16.1 m (53 ft), beam 7.9 m (26 ft), depth 3.2 m (10 ft) and load 223.8 metric tons of displacement. The foremast is 9.7 m (32 ft) high, the mainmast is 15.9 m (52 ft) and mizzen mast is 10.4 m (34 ft). The replica was declared by Jose Maria Martinez-Hidalgo, a Spanish marine historian, to be the most authentic replica of the Santa María in the world during the ship's coronation on 12 October 1991.

Based on this passage, what type of wood was the santa maria made of?
